Description of the Invention (1) <Invention Field> The present invention generally relates to the field of telephone and data communication. More specifically, the present invention relates to the use of non-telephone networks, such as low-voltage power line distribution networks, as telephone and data lines that can be reconfigured on demand. <Background of the Invention> The current telephone network provides telephone and data communication services to many individual users. Each user is assigned a unique phone number and there is a dedicated line or user from the user's location to the telephone company's central processing room. Internet is provided. Typically, the distance from the user's location to the central processing room is about a few miles. The central processing room provides connections between those individual users and other telephone network users. Each user's user network may have many telephones and other communication devices. For example, fax machines and modems are connected to the user network. However, since these devices are all connected to the same telephone line, only one telephone call can be set at any one time * For example, when using a telephone / fax machine, call through a voice or via a fax machine Of fax communications, one of which can be maintained at any given time. Similarly, when using a combined telephone / modem, one of which can be maintained by voice call via the phone or by the modem's data call • Often, a voice call * can be set up and a simultaneous call A data call or fax call is desirable, such as when two people are talking and one party wants to transmit a fax or data that is discussed in more depth to the other party. As the single line is assigned to each user * the only solution ---------- J installed-(Please read the precautions on the back before filling in this I) ^ ff i -line-This paper size applies Chinese Family Standard (CMS > A4 specification (2 〖〇297297mm) -4 A7 printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs __B7_ V. Description of the invention (2) The method is to end the voice call and transmit the true Or information, and then start a subsequent voice call. This method is extremely inconvenient. For the above simultaneous communication problem, a more advanced solution is to provide more than one dedicated line for each user. When the user has two When a dedicated line is provided, one dedicated line can be used for voice communication and the other can be used for fax or data communication at the same time. The rule of multiple dedicated lines to each user also addresses the problem of simultaneous voice communication to different groups. For each user, the provision of multiple dedicated lines also addresses the problem of simultaneous voice communication for different groups. When there is more than one person at the user's location who wishes to send a voice call to a different group This happens. Then everyone can ~ start different voice calls on each different subscriber line. * One disadvantage of providing multiple lines to each user is the increased system complexity and the bandwidth required to manage such a system. A more important disadvantage for users is the increased cost of connecting additional lines-especially the fact that the second (or additional) line can only be used very rarely and very shortly. The cost disadvantage of connecting the second line is The same can be applied to many examples of single-line structures. This is due to the fact that installing and starting a telephone line involves a considerable amount of complicated procedures. When those telephone lines are only needed in a short-term, temporary time · For example In temporary housing, college dormitory 'summer house or similar cases, it is often inconvenient to install and activate a telephone line, and only remove it after using it for a while. <Objective of the Invention> It is an object of the present invention to provide a system For the use of non-paper paper music scales applicable to China National Standard (CNS) A4 specifications (2! 0X 297 mm) ~ —. 1 ^ Binding -------- " Thread ---- ί (Please read the precautions on the back before filling out this page) Printed by the Zhengong Consumer Cooperative of the Central Government Bureau of the Ministry of Economic Affairs; * K; ; P8 Α7 _____ Β7 V.

That is, at the user's location. 210 sets the first phone of a call to be dynamically assigned a line. When they set up a subsequent call, all subsequent phones at location 210 are dynamically assigned to a line. Alternatively, a single phone number may be assigned to the transformer 200. All The phone connected to the transformer 20G is assigned a suffix identification code, which is attached to the phone number of the transformer 200. In this example, the location 210 does not have to pay for a continuous • dedicated line subscriber loop fee. Instead, the location 210 A telephone line is required, and plugging in the telephone equipment results in a "telephone line configuration." According to another embodiment of the present invention, the use of suffixes may all be removed together and replaced with a unique telephone equipment system. The system has an identification number hidden in each phone. This is similar to the phone commonly used in cellular telephone systems Material serial number usage.
